MENLO PARK, Calif., May 10, 2022 (GLOBE NEWSWIRE) -- AN2 Therapeutics, Inc. (Nasdaq: ANTX), a clinical-stage biopharmaceutical company focused on developing treatments for rare, chronic, and serious infectious diseases with high unmet needs, today reported financial results for the quarter ended March 31, 2022.

“Over the past several months, we made significant progress on many key initiatives, executed a successful upsized IPO, strengthened our board with new members, and progressed the clinical and regulatory strategy for our lead product candidate epetraborole,” said Eric Easom, President and Chief Executive Officer. “With these advances in our development program and a strong balance sheet, we believe we are well-positioned to execute our objectives.”

First Quarter & Recent Business Updates:

Raised Total of $79.4 Million Through Upsized Initial Public Offering. In March, AN2 Therapeutics successfully completed an upsized initial public offering of $69.0 million and on April 12, 2022, the Company received an additional $10.4 million from the underwriter’s full exercise of its option to purchase additional shares. The Company plans to utilize proceeds from the financing to fund the development of epetraborole for treatment-refractory non-tuberculous mycobacterial (NTM) lung disease caused by Mycobacterium avium complex (MAC), the expansion of epetraborole in treatment-refractory MAC lung disease to other key global markets, and the further development of the Company’s boron chemistry drug discovery platform, as well as other general corporate purposes.

Reported Phase 1b Data for Oral Epetraborole. In February, AN2 Therapeutics announced topline results from its Phase 1b dose-ranging study evaluating oral epetraborole in healthy volunteers at doses ranging from 250 mg to 1,000 mg administered for up to 28 days. There were no severe or serious adverse events and safety and pharmacokinetic results support further clinical development of epetraborole in NTM lung disease. Pharmacokinetics were shown to be generally linear and predictable, consistent with previous studies.

Epetraborole IND Cleared, Granted QIDP, Fast Track and Orphan Drug Designation. In January, AN2 Therapeutics reported that the U.S. Food and Drug Administration (FDA) cleared the Company’s Investigational New Drug (IND) application for epetraborole, granted Fast Track designation to investigate epetraborole for treatment-refractory MAC lung disease, and designated epetraborole as a Qualified Infectious Disease Product (QIDP) for treatment-refractory MAC lung disease. In February, the Company announced that the FDA granted epetraborole orphan drug designation for the treatment of infections caused by NTM.

Expanded Company’s Board of Directors. During the quarter, AN2 Therapeutics appointed Dr. Mel Spigelman to its Board of Directors. Dr. Spigelman is a leader in the area of Mycobacterium antibacterial drug research and development, serves as the President and CEO of the Global Alliance for TB Drug Development, and is the Co-Chair of the Working Group on New TB Drugs of the Stop TB Partnership. In May, the Company appointed Maggie FitzPatrick, a corporate affairs, communications and business operations leader, to its Board of Directors. Ms. FitzPatrick previously served as Global Chief Communications Officer and led public affairs at Johnson & Johnson. 

Advancing Epetraborole Clinical Development. AN2 Therapeutics has commenced start up activities for its pivotal Phase 2/3 trial in treatment-refractory MAC lung disease, which is expected to begin in the first half of 2022. Topline results for the ongoing Phase 1 study evaluating epetraborole in renally impaired subjects is expected in the second half of 2022. The Company has also initiated planning activities for its Phase 1 safety and pharmacokinetics study of oral epetraborole in healthy volunteers in Japan, in anticipation of potentially studying epetraborole in Japanese treatment-refractory MAC lung disease patients in the future.

Financial Results for First Quarter 2022:

  • Research and Development (R&D) Expenses: R&D expenses increased for the three months ended March 31, 2022, compared to the same period during 2021 due to higher clinical trial activity, additional R&D personnel and related stock-based compensation expense, increased manufacturing activity for our clinical trial supplies and higher outside consultant costs related to our research and development activities. 
  • General and Administrative (G&A) Expenses: G&A expenses increased for the three months ended March 31, 2022, compared to the same period during 2021 due to additional G&A personnel and related stock-based compensation expense, higher outside legal and accounting professional service costs and increased consulting services.
  • Cash Position: Cash, cash equivalents and short-term investments totaled $118.4 million on March 31, 2022. The Company expects that current cash, cash equivalents and investments, including net proceeds from the underwriters’ over-allotment option exercised in April, will be sufficient to fund its operating expenses through mid-2024.
